16 bits per sample which uses pulse code modulation (PCM) [1] The Audio compression basically utilizes MPEG 1 standard which is a generic audio compression standard. Audio compression in MPEG unlike vocal coders have coders known as encoders that do not assume the nature of source which generates

MPEG-1 and MPEG-2 Layer II Audio Encoding
https://www.loc.gov/preservation/digital/formats/fdd/fdd000338.shtml
MPEG-1 and MPEG-2 Layer II Audio Encoding. Description. Lossy audio compression that derives from the MUSICAM audio codec. This format may be referred to as MP2 and employs perceptual compression. This means MP2's compression takes out information that is imperceptible in the human auditory range. MP2 is the dominant audio …
MPEG/Audio Compression - SlideShare

Introduction What does MPEG-1 Audio provide? A transparently lossy audio compression system based on the weaknesses of the human ear. Can provide compression by a factor of 6 and retain sound quality. One part of a three part standard that includes audio, video, and audio/video synchronization. 4. Technical Overview 5.
A Tutorial on MPEG/Audio Compression

1.1 MPEG/audio Features and Applications MPEG/audio is a generic audio compression standard. Unlike vocal-tract-model coders specially tuned for speech signals, the MPEG/audio coder gets its compression without making assumptions about the nature of the audio source. Instead, the coder exploits the perceptual limitations of the human auditory system.
9 – Audio compression in MPEG – Leonardo Chiariglione

Indeed ITU-R, who does need audio compression for its digital audio broadcasting standards, prefers to rely on external sources, including MPEG. MPEG-1 Audio. Those interested in knowing why and how a group – MPEG – working in video compression ended up also working on audio compression (and a few more other things) can look here. The kick off of the MPEG …
Audio Compression - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/computer-science/audio-compression
The term MP3 comes from MPEG-1, layer 3; the MP3 spec is part of the MPEG-1 standard. That standard [Bra94] defined three layers of audio compression: • Layer 1 (MP1) uses a lossless compression of subbands and an optional, simple masking model. • Layer 2 (MP2) uses a more advanced masking model. •
